MOULDING FOR SUSPENSION MOUNTING AND DECORATION PURPOSES o. H. BLICK Filed Feb. 12. 1971 INVEN'RDR OWE HBL/CK ATTUVfli-fY United States Patent Ofiice US. Cl. 52-222 7 Claims ABSTRACT OF THE DISCLOSURE A moulding for attachment to a wall or ceiling and receiving a strip wrapped in the end portion of a wet stretched or elastic ceiling covering or supporting a coifered ceiling for decorative purpose.

This invention refers to a moulding for suspension mounting and decoration purposes, said moulding being made from sheet metal, aluminum, rigid polyvinyl chloride or similar material and intended to be used with Wet stretched and elastic coverings for ceilings and so called cotfered ceilings, which moulding is mounted around the walls of the room or in the ceiling of the room thereby forming either a means of attachment for a strip wrapped in the end portion of the stretched covering or forming stores for so called cotfered ceilings.

The main object of the invention is to provide a moulding for suspension mounting and decoration purposes, which moulding is easily mounted and which in a simple and economical manner enables mounting of stretched coverings for ceilings as well as storing of so called coifered ceilings while at the same time providing an attractive design. The construction of the moulding further enables removal of the ceiling covering from the moulding in desired locations in order to get access to electrical lines or the like disposed above the covering, which removal has hitherto made it necessary to remove the entire covering.

In the following reference is made to the drawings in which FIG. 1 shows the moulding mounted in a corner between the ceiling and the wall.

FIG. 2 is a perspective view of the moulding with an attached ceiling covering.

FIG. 3 shows two mouldings mounted together.

FIG. 4 illustrates two mouldings mounted on an intermediate part and FIG. 5 shows the moulding with a stored so called coifered ceiling.

The moulding 13 to be mounted in ceilings 1 or in walls 2 is provided with a horizontal attachment surface 3 for securing to the wall 2, said attachment surfaces being disposed at right angles relative to each other. At the lower part of the mouldings vertical attachment surface the moulding continues from the wall in a sliding surface 5 having essentially quarterly circular form. At the lower horizontal part of the sliding surface a horizontal lower moulding part 7 is provided, said moulding part being connected to a vertical, upwardly directed moulding part 8. A lock lip 9 extends from the vertical moulding part 8 and forms with the lower moulding part 7 an angle slightly smaller than 360, thereby forming a diverging groove in the moulding the width of the bottom a of the groove being smaller than the width of the opening b of the groove.

A strip 11 is provided for attaching the ceiling covering 12 to the moulding, said strip extending along the length of the moulding and being wrapped in the covering. The strip with the covering wrapped therearound is pressed into the groove, whereby the thickness of the strip and the ceiling covering wrapped therearound being larger than the width by the bottom of the groove but smaller than the width by the opening of the groove. Further, the width of the strip is larger than the width of the lock lip. When the strip together with the covering is mounted in the groove the covering exerts a force which tends to press the strip into the groove. Due to the width of the strip this latter does not reach the bottom of the groove, whereby a wedge action takes place, which effectively locks the ceiling covering to the moulding. The strip 11 and the sides of the lower part of the moulding 7 and the lock li-p 9 facing each other can entirely or partly if desired be provided with teeth in order to give additional security to the lock.

The rounded form of the sliding surface 7 assists in putting the strip 11 into the groove 17. When the strip is inserted in the groove the former is pushed into the moulding towards the vertical attachment surface 4, whereupon the strip slides over the sliding surface into the groove 17.

The moulding may be provided with a supporting lip 10 forming the upward extension of the vertical supporting surface 8. The height of the supporting lip is such that the ceiling covering 12 contacts the same and thereafter deflects downwardly towards the strip around which it is wrapped. This supporting lip makes the contact between the ceiling covering and the moulding more attractive.

The moulding 13 may also be provided with a hook forming part 6 extending from the lower moulding part 7 towards the wall and terminating a slight distance from the wall in a vertical, upwardly directed hook. The purpose of the hook forming part 6 is to mark a shadow effect against the wall which in turn enables covering of the walls before or after the securing to the ceiling. Other purposes of the hook forming part is to reduce visual elfect of defects in not completely straight walls and to act as a hook for suspension mounting of articles, paintings or the like and to give a hidden mounting possibility for telephone cables, cables for TV-sets or the like.

The above described mounting of the ceiling covering 12 in the moulding provides a secure attachment means for most known types of coverings for ceilings, wet

stretched as well as elastic. Wet stretched and elastic coverings for ceilings can be demounted without affecting the moulding by releasing the strain in these.

FIG. 3 shows a pair of mouldings mounted together by means of the plane parts 4 thereof and thus attached to the ceiling 1 through plane moulding parts 3. The moulding is used in the described mannerto part surfaces of the ceiling where the dimensions of the room makes mounting of the whole ceiling surface in one continuous covering impossible.

FIG. 4 illustrates two mouldings mounted on an intermediate part 15 that serves both as an attachment surface for said mouldings and determines the distance between the mouldings in order to define in its mounted state in the ceiling 1 of the room a groove and a guiding means for subsequent mounting of story high, prefrabricated partition wall sections 14. The thickness of the intermediate part 15 is slightly smaller than the height of the plane parts 4 of the mouldings. The attachment mounting to the ceiling is alternatively effected, as shown in FIG. 4, through the intermediate part 15 or the plane parts 3 of the mouldings.

Advantageously the present moulding is also used for different types of so called coffered ceilings 16 (FIG. 5), which are put upon the part 10 of the moulding. If desired, the space in the groove 17 is thereby used to receive lines for electricity, telephone or the like.

I claim:

1. A ceiling comprising a moulding strip having a flat ceiling attachment surface having openings therein, attachment means extending through said openings, a wall attachment surface integral with and extending normal to 3,719,013 Patented Mar. 6, 1973 said ceiling attachment surface, a fiat molding part extending normal to and being integral with said wall attachment surface and a lock lip extending from said molding part at a slant to and over a portion of said wall attachment surface providing a groove therewith, said wall attachment surface having a straight portion adjacent said ceiling attachment surface and a laterally curved portion extending from said straight portion to said moulding part, a strip having a ceiling covering wrapped therearound, detachably mounted in said groove and being thicker than the bottom of said groove, but smaller than the mouth of said groove and wider than the width of said lock lip.

2. A ceiling as claimed in claim 1 wherein said strip is provided with teeth.

3. A ceiling as claimed in claim 1 wherein said lock lip forms an angle of less than 360 degrees with said adjacent portion of said wall attachment surface.

4. A ceiling as claimed in claim 1 wherein said wall attachment surface has a straight portion adjacent said moulding part and an inner sliding surface between said straight portions of said wall attachment surface which sliding surface is essentially of a quarterly circular lateral form on a radius of approximately one-half the width of said moulding part.

5. A ceiling as claimed inclaim 1 wherein a supporting lip extends in line width and from said moulding part, supporting said ceiling covering thereon.

6. A ceiling as claimed in claim 4 including a hook extending from said second straight portion of said wall attachment surface below and towards said sliding surface.

7. A ceiling as claimed in claim 4 wherein the facing portions of said wall attachment surface second straight portion and said lock lip are provided with teeth.
